Not sure if these were used in WW2 or not, but if so, what about having these available... there are many times when squaddies are GVing it, (I hate being in a GV and almost NEVER do it) and I come in overhead to try and help mark the GVs for the squad... a rack of smoke rockets would sure make this task mroe viable, and be realistic... (if indeed smoke was used this way in WW2)
